Hawaiian Dredging was hired to install additional lanes along the heavily traveled Pearl City and Waimalu Viaduct in Honolulu, Hawaii. The project was designed to increase the capacity of the H1 freeway for Westbound commuters during the afternoon rush hour.
FasTrac 303 Cement and FasTrac Polymer were instrumental in the repair, allowing the construction crews to minimize downtime on the busy highway.
Sections of the bridge deck were removed and replaced each night to avoid any impacts to the afternoon and morning rush hour traffic. High pressure water blasting equipment was used to demolish old concrete, leaving a hole and exposed rebar. Then, the hole was filled with high performance rapid setting concrete made with FasTrac 303 Cement and FasTrac Polymer.

FasTrac 303 Cement
FasTrac 303 Cement is a one-component, rapid setting, low shrinkage, extendable cement that is used when high early strength gain, low permeability, and latex modification is required. FasTrac 303 Cement is mixed with aggregate, latex, and water on site for large scale horizontal concrete repairs and form and pour vertical applications.
Features/Benefits
- Shrinkage compensation minimizes cracking from drying shrinkage
- Reduced permeability and improved overall durability
- Excellent resistance to freeze/thaw
